This research study analyzes the problem of waste water from the burning of palm trees which are used as fuel for power generation of palm ash. It is used to ferment biogas as a fuel for power generation where a large amount of wastewater from the gas digester is completed. The wastewater is then pumped out of the gas digester. Biological in large quantities Therefore to study the analysis of wastewater to find a method for designing a wastewater treatment system from high voltage systems from the corona discharge principle when adding ozone it is necessary to analyze the chemical effects of the wastewater according to the standard values of the Department of Industrial Works.

Objectives of this study are (i) to investigate characteristics of a fuel injector and to establish the characteristic correlation for correcting the fuel injection rate calculated from the control signal of a fuel injector and (ii) to design and fabricate the fuel consumption monitoring system by measuring the control signal of fuel injector in conjunction with considering the obtained characteristic correlation to enhance accuracy of the measured fuel consumption rate. The characteristics of a fuel injector (maximum fuel injection rate of 270 cm3/min) e.g. engine speeds percentages of injector’s duty cycle and pressure differences between fuel rail and intake manifold were experimentally investigated on a test set in the laboratory. The study found that when the engine speed increased the fuel injection rate increased. When the percentages of infector’s duty cycle increased the increasing ratio was less than the one-to-one increasing ratio as a case of the ideal. Moreover when the pressure difference increased the fuel injection rate increased. After that the fuel consumption monitoring system was designed and fabricated based on the Arduino Mega 2560 microcontroller. Trip distance was measured by a GPS module. The real-time fuel consumption rate could be shown on a LCD display. All recorded data were stored onto a SD card for further data analysis. Finally the on-road-test validation was conducted by on the 2011 Mitsubishi Triton installed with the 4-cylinder gasoline engine with total displacement of 2351 cm3. It was found from that the average discrepancy of the measured fuel volume was ± 1.88% compared to the actual fuel volume obtained by measuring a decreasing volume of consumed fuel.

The purposes of this research were to investigate anaerobic digestion of concentrated food waste in biogas production system at mesophilic temperature (37 C). The effect of grinding and pH controlled at 6.20 and 7.00 on methane production were also studied. It was found that the ability of mix bacteria which had initial concentration of 2100 mg/l for digesting concentrated food waste with grinding was higher than that without grinding because of the increase in surface area (about 1.37 time). In this system the optimum condition for bacteria growth was found at pH 7.00. Under optimal condition the digestion efficiency in term of chemical oxygen demand (COD) removal was 18.81% higher corresponding to an increase in methane production rate (19.10%) than other conditions

Thesis is the development of radio-controlled lawn mower which can move and cut the grass in the desired environment and dangerous to human. The objective is to develop a radio-controlled lawn mower. The results showed that the rate of fuel consumption of controlled lawn mower in to cutting grass. The height of the grass at 6 8 and 10 cm. It has the average fuel consumption is 113 117 and 123 ml. The average time in the mowing is 6.6 8.01 and 9.69 minutes

This article presents a collection of studies relating to the development of technologies using hydrogen with compressed natural gas or Hydrogen-enriched Compressed Natural Gas (HCNG). Regarding to the issues of mixing ratio the data show that the appropriated amount of hydrogen falls between 20%-30% by volume in order to balance any tradeoff between engine performance and emissions. The equivalent ratio can be adjusted to be as low as 0.5-0.6. The ignition timingmust also be retarded (Ignition Delay) by averagely 5 degrees of crankshaft rotation to compensate for the change of burning speed. Theuse of 20%-30% of hydrogen by volume decrease both HC and NOx as compared to the use of CNG alone. In terms of the fuel system design the individually-stored gas injection system is of interest. It provides flexibility especially for the adjustment of the fuel composition for optimum ration in any operating conditions. But at present there is no commercial development of such system.
